Answer these questions to see if you qualify for Irish citizenship by descent
What is Irish Citizenship by Descent?
Irish citizenship by descent allows individuals with Irish heritage to claim Irish citizenship through the Foreign Births Registration (FBR) process. Unlike many other countries, Ireland recognizes citizenship by descent for up to 2 generations - meaning you can qualify through an Irish parent or an Ireland-born grandparent.
🇮🇪 Key Benefits of Irish Citizenship
- EU Citizenship: Live, work, and study in any of 27 EU countries
- 187 Visa-Free Destinations: One of the world's strongest passports
- No Residency Requirement: Never need to live in Ireland
- Fast Process: 6-18 months vs years for naturalization
- Pass to Children: Your children automatically become Irish citizens
Important: Ireland's 2-Generation Limit
Ireland only allows citizenship by descent for:
- 1st Generation: If your parent was an Irish citizen when you were born
- 2nd Generation: If your grandparent was born in Ireland or Northern Ireland
⚠️ Great-grandparents don't count: If your great-grandparent was Irish but your grandparent wasn't born in Ireland, you cannot directly claim Irish citizenship. However, if your grandparent registers for Irish citizenship first, then you could potentially apply.
